To all whomit may concern Be it known that 1, FRANK X. MLLER, a

citizen of the United States, residing at Buf-- falo, in the county of Erie and State of New York, have invented new and useful lmprovements in Hose-Couplings, of which vthe following is a specification. 'l

This invention relates to a hose coupler and has for its object to provide a coupler for this purpose which can ,be produced at comparatively low cost and which is simple and'durable in construction, eicient in operation and/capable, of being easily manipulated for coupling o`r uncoupling two sections of a hose.-

In the accompanying drawings: Figure 1 is a longitudinal section of a hose coupler embodying'my improvement and showing the same applied to two sections of a hose for connecting the same. Figs. 2 and 3 are vertical' transverse sections taken in the correspondingly numbered lines in Fig. 1'. Fig. 4 is aside elevation of the conducting tube of one of the cou'pler sections showin lits condition before being assembled wit the remaining parts of the respective section.`

Fig. 5 is a front end view of the ferrule forming part of one of the coupler sections.

Fig. 6 is a vertical transverse section taken in line 6-6, Fig. 4:. Fig.'7 is a side elevation of the ferrule of one of the coupler sections, showing its condition before being assem'bled with the companion members of thel respective sections. Fig. 8 is a side elevation of the clamping sleeve of one of the coupler sections.

Similar characters of reference indicate corresponding parts throughout the several views.

In its general organization, this hose cou-y pler comprises two sections which are identical in construction and which are adapted 'to be connected respectively with two sections 1, 2, of a hose and they are also adapted to be connected detachably with each other by a screw threaded union joint.

Each of the coupler `sections comprises a ferrule,v a clamping sleeve, a head and a conducting tube. Each of the ferrules is of substantially tubular form and preferably comprises an enlarged front part or body 3, a reduced rearwardly-tapering or conical rear part or shank 4, and a contracted neck v 5 connecting the rear end of the body with the front end of the shank.- This body, shank and neckvof ythe ferrule are preferably constructed of one piece of'sheet metal and the body-portion of the ferrule has its periphery Vconstructed to form an external or male screw thread 6. The rear end 7 of the shank 'is contracted so as to form a rearvvwardly-facing shoulder 8 on the exterior .of the shank. rlhe conical or tapering shankof each ferrule. is inserted into the end of one of the hose sections, which latter being usually of a iiexible character, is distended somewhat. vThe clamping sleeve 9 of this coupler section is adaptedto secure the end of the hose section on thev respective conical or tapering shank and is provided'on its front part with an internal or female screw v thread 10 which engages with the external thread of the ferrule, while its rear end is provided with an inwardly-projecting bead or annular flange 11 which is adapted to engage with that part of the respective hose section surrounding the companion conical shank. By screwing the clamping sleeve tightly on the body of the ferrule after the hose end has been slipped over the companionshank, the bead or flange of the clamp'- of the hose section and causes thelatter to be firmly gripped between the bead l1 of the clamping sleeve and the shank of the ferrule, so that these parts are firmly united and prevented from becomingA detached while 'the hose is in u se. The clamping sleeve together with itsl screw thread and Vclamping bead are preferably made of sheet -ing sleeve is pressed against the outer side the latter. At the outer front corner of the l head, between the body and disk thereof the same is provided with an outwardly-projecting annular bead 15 which engages with' the front end of the ferrule.` At its rear v end the body of the head is provided with two lips 16 which pass through correspond- I ing openings 17 formed in thelneck of the lar and fastening lips of the head are ally formed in one piece from a single sheet of metal.

The conducting tube comprises a tubular front part 178 of comparatively large diameter and a tubular rear part 19 of somewhat smaller diameter, forming a rearwardly facing shoulder 20 between the front and rear parts of this tube. The rear part of the conducting tube -is passed rearwardly through the centering collar of the head and the contracted rear end of the companion shank until the shoulder between the front and rear parts of this conducting tube engage with the front side of the disk 14 of the respective coupler section, after which the rear end 21 of the conducting tube is folded outwardly and forwardly around the contractedrrear end of the companion shank, so as to form a seam between the same, as shown in Fig. 1, thereby securely uniting the conductf ing tube and ferrule and assisting in confining the head between the conducting tube flange 24 which is preferably constructed in the form of a bead by reversely bending or doubling the outer end portion of the conducting tube upon itself. All of the parts of the conducting tube just described are also preferably constructed from a 4single sheet of metal.

Two coupler sections constructed in this' manner and applied to the opposing ends of two hose-sections may be detachably connected with each other in various ways but preferably by the means which are shown in the drawings and which comprise a ymale Icoupling sleeve 25 `mounted on the enlarged front part of pne of the conducting tubes and engaging its front and rear ends with the flange of the conducting tube and the disk of the companion head and provided on its periphery with an external or male screw thread., This male coupling sleeve maybe held against turning on the respective conducting tube solely by friction but the same is preferably additionally held against turnlng on its conducting tube by means of keys 26 formed on the enlarged front part of the uprovided at its rear end with an inwardlyprojecting annular iiange 29 which is mounted loosely uponthe periphery of the enlarged front part of the other conducting tube of the hose coupler between the front flange thereof and the disk of the companion head, as shown in Fig. 1. In order to produce a tight joint between the opposing ends of the two conducting tubes, a packing ring or washer 30 of rubber-or` any other suitable material is inserted between these flanges, so that upon 'tightening the coupling sleeves 25, 28, the flanges of the conducting tubes will be drawn firmly against opposite sides of the packing ring or washer and effectually prevent leakage. The male bushing and the female coupling sleeve practically form a union whereby the two sections of the hose coupler may be readily connected or disconnected. These members of the union are also preferably constructed of sheet metal 1n any sections of hose are connected in this manner by. my improved coupler, a practically free and smooth passage is formed through the coupler which places the hose sections in communication with each other.

Inasmuch as all of the parts of this hose coupler aremade of sheet metal the same can be made very light, durable, compact and at comparatively low cost,'thereby rendering the same particularly suitable for connecting the sections of garden hose, although the same may also be used for other kinds of hose or tubes.

Furthermore, this coupler has no laterally projecting parts which are liable to catch on `the ground or interfere with obstructions when drawn over the ground, and this also permits of handling the hose freely7 without "liability of injuring the hands and also per-- mits vof compactly reeling the hose on a rack without liability of the coupling injuring the hose.
